doesnt raft have a problem that it assumes no hysteresis? and that in general you can construct a latency graph that deterministically causes a permanent lock in the leadership election phase?
I'm not sure I fully understand your question, but the heartbeat time outs and leader election time outs are static. And yeah if you make votes and heartbeats time out in a way that nobody can be elected, then raft can't make progress.
I've never had this be a problem in reality but AWS has a pretty good backbone. Maybe if you were running it over a pretty unreliable network this would be an issue?
